If it's got a 180 degree field of view and it's 3d video, I don't think it's much of a stretch

If you're the kind of person that never moves and faces one direction then yes, it wouldn't be much of a stretch to call this a form of reality.

I'm lucky enough to not be in that situation, so this is more like portable 3D video to me. But that doesn't brand as well.

Is it really virtual if it is recorded actual reality?

Depends on the aspect ratio of the video, really. /rimshot
